Original task: Post a bilingual system message into the group chat when a member leaves via POST /api/conversations/:id/leave, with real-time delivery via Socket.IO and rendering in the chat thread. Findings: - The leave handler in artifacts/api-server/src/routes/conversations.ts already inserts a `member_left` system message (and `admin_promoted` when a successor is auto-promoted) and emits via Socket.IO using insertAndEmitSystemMessage. Direct conversations and last-leaver cleanup paths are correctly skipped. - artifacts/teaboy-os/src/pages/chat.tsx renderSystemMessage already handles `member_left`, `admin_promoted`, and `adminPromotedAfterLeave`. - Bilingual locale keys exist in src/locales/en.json and ar.json under chat.system.memberLeft / adminPromoted / adminPromotedAfterLeave. Change made: - Extended the MessageWithSender.kind enum in lib/api-spec/openapi.yaml to include `member_left` and `admin_promoted` (previously only user/group_renamed/members_added/member_removed were declared). - Re-ran `pnpm --filter @workspace/api-spec run codegen` to regenerate api-zod and api-client-react schemas so the spec, runtime validation, and client types stay in sync. - Verified `pnpm -w run typecheck` passes across all packages. No behavioural code changes were necessary; the feature was already implemented end-to-end and only the API spec enum needed to catch up. Replit-Task-Id: 40fccb3a-4fc0-4ad7-a6e9-d1ac67ef7769
